Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294986640, here are decompositions:

11 + 4294986629 = 4294986640
149 + 4294986491 = 4294986640
167 + 4294986473 = 4294986640
251 + 4294986389 = 4294986640
389 + 4294986251 = 4294986640
419 + 4294986221 = 4294986640
431 + 4294986209 = 4294986640
443 + 4294986197 = 4294986640

Showing the first eight; more decompositions exist.
